Geibel Catholic Junior-Senior High School is a private, Roman Catholic high school in Connellsville, Pennsylvania. It is located in the Roman Catholic Diocese of Greensburg.

In 1969, Bishop William G. Connare began to develop plans to build a new, modern high school that would serve students from Northern Fayette and South-Central Westmoreland Counties. The Rev. Henry Geibel, former priest of the nearby Immaculate Conception Roman Catholic Parish, where classes were held previously, until the school enrollment over-exceeded its capacity, purchased property on which the school would be built in the Hillcrest section of Connellsville Township. Ground was broken on March 6, 1963. The facility cost $1.2 Million to construct and was completed for the start of classes in the winter of 1964. Rev. Geibel died before the school was completed. The school was named in his honor, the Father Geibel Memorial High School. A football field was added in 2004. The Middle School Concept, adding grades 7 and 8, was completed for the start of the 2006–07 school term. The current school name is Geibel Catholic Middle-High School.
